How this service works
Caller E2E - x402:
Output
Returns a JSON object containing an 'ok' boolean field indicating whether the x402 caller end-to-end flow is operational. A successful response with ok: true confirms the paid endpoint is reachable and functioning correctly.
Example use cases
Verify x402 payment flow works
“Can you hit the x402 Caller E2E state endpoint and confirm it returns ok? I want to make sure the payment protocol is working end to end.”
Test paid API integration health
“Check the state of the x402 e2e caller test on miniup.app — I need to know if the paid call goes through successfully before I build on top of it.”
Debug x402 micropayment failure
“I'm having trouble with x402 payments — can you query the Caller E2E state endpoint and tell me what it returns so I can diagnose whether the issue is on my side or theirs?”
Technical details
Endpoint
GEThttps://functions.miniup.app/caller-e2e-x402/stateWhen to prefer
Use this endpoint when you need to verify that an x402 micropayment-gated API call works correctly end-to-end, especially when testing or debugging x402 protocol integrations. Prefer this over generic health checks when specifically validating paid API access patterns with the x402 standard.
Side effects
- Payment not sent or rejected — 402 Payment Required returned if x402 payment header is missing or invalid
- Endpoint unavailable — 5xx error if miniup.app infrastructure is down
- Malformed request — 400 if request structure doesn't match required schema
- Network timeout — endpoint may be unresponsive under load
